You need to kill time in the airport so how do you go about it? Often you find a restaurant and get a
drink or something to eat. At many airports, you will soon be doing your ordering and paying through an IPad rather than a waiter. Then, while you wait for your order to arrive, you can kill more time surfing the web on the IPad.

It’s all part of a movement towards improving airport services and updating facilities.
